Not all welding machines are fully equipped with all the necessary accessories: cables, holders, masks. All this has to be purchased additionally. Particular attention should be paid to the choice of wire. Also, often the cable included with the welding machine is very short, so they buy an additional one of the required length.
The welding cable is a flexible conductor; designed to supply current to the welding machine or to the holder holding the electrode, as well as to the ground clamps.
A unit of any type will operate smoothly and will serve the owner for a long time if the conductor is selected correctly. In the article we will consider the important characteristics of this product: welding cable KG, its characteristics and types.

Cable voltage loss calculator
When designing power lines of long length, the choice of conductor according to the cross-section and material of the current-carrying cores is made not only on the basis of the power of the connected load, but also taking into account the voltage loss (∆U).
Formulas for calculating the voltage drop in a cable line
Example No. 1 Calculation of line voltage loss (between phases)
Initial data
A line 100 meters long is connected to a three-phase source (nominal voltage - 380 V, current - 16 A, shift angle - 180) of electric current using a power conductor of the VVGng brand 4x6 mm sq. with inductive and active resistances of 0.09 and 3.09 Ohm/km, respectively.
Calculation
According to the formula shown in the picture, the voltage drop will be equal to:
∆U = √3•I• (R•Сosȹ•L+X •Sinȹ•L) = 1.73•16•(3.09•0.95•0.1+0.09•(-0.75 ) •0.1)=27.68•0.287=7.93 V.
Thus, in this case, a voltage loss of 7.93 V or 2.09% of the nominal value is observed in the laid section.
Example No. 2 Calculation of phase voltage losses (between phase and zero)
Initial data
A line 50 meters long is connected to a single-phase power source (rated voltage - 220 V, current - 5 A, shift angle - 180) of electric current using a power conductor brand VVGng-LS 3x4mm sq., the inductive and active resistance of which is 0.095 and 4.65 Ohm/km, respectively.
Calculation
According to the formula shown in the picture, the voltage drop will be equal to:
∆U = 2•I• (R•Сosȹ•L+X •Sinȹ•L) = 2•5•(4.65•0.95•0.05+0.095•(-0.75) •0.05 )=10•0.216= 2.16 V.
Thus, in this case, a voltage loss of 2.16 V or 0.98% of the nominal value is observed in the laid section.
Important! According to GOST R 50571.5.52-2011, the maximum permissible voltage drop on lighting devices powered from the general power supply system should not exceed 3% of the rated value. For other devices, it is allowed to reduce the supply voltage relative to the nominal by 5%. If these standard values are exceeded, devices and equipment connected to the network may not operate correctly (their power and performance are reduced, spontaneous shutdown is observed). In some cases, if electrical appliances have controllers that are very sensitive to mains voltage, the latter may fail, thereby rendering the heating gas boilers, refrigerators, and pumping stations they control unusable.

Formula for calculating copper content in cable
In order to calculate the copper content in any cable, you need to know the following parameters:
D is the diameter of one core or S is the cross-section of the core,
p is the density of copper/aluminium, pcopper can be taken equal to 8900 kg/m3, aluminum we will take 2700 kg/m3
Cook - cable twist coefficient,
So, if you know the cross-section of the copper core, then the formula for the copper content (M) in the cable will be as follows:
If you don’t know the cross-section, it’s easier to measure the diameter of the cores and use this formula:
To correctly measure the diameter and, if necessary, calculate the cable cross-section, use our article “How to determine the cable cross-section by diameter?”
The twist coefficient (Kuk) is used for cables with multi-wire conductors, for cables where the conductors are twisted into pairs, quads, etc.
Twist factor is the ratio of the length of the twist element in a twisted cable product to the length of the product (GOST 15845-80)
For solid cores Kuk = 1, the twist factor for stranded cores can be found in RD 16.405-87 “Calculation of masses of cable products materials” (Table 6) or the newer standard STB 2194-2011 (Table 6-7) similar to the first. On our website you can download STB 2194-2011 by clicking on the link.

Cable diameter
This characteristic of cable products is measured by the outer sheath. The value of the diameter is influenced by such design features of the conductor as the thickness of the outer insulation, the number and cross-sectional area of the conductors. The outer diameter varies from 5-5.5 to 80-100 mm.
Thus, using both an online cable calculator and calculation of its weight and cross-section using the above methods, you can independently calculate the number and select the brand of wires (VVG, AVVG VBBShV, PVS, etc.) required to connect a cottage or country house home to the nearest power line.

Copper content in ball screw wires
On a note . To calculate the weight of a cable without the help of an online calculator, use the following simple formula: Vk=πr2ρln, where r is the radius of the core, n is the number of cores, l is the length of the conductor, ρ is the density of the core material (for copper it is 8.9 g/cm3 , for aluminum –2.7 g/cm3).

Table of weight of copper, aluminum, lead in cables and wires
If the cable has a sheath (lead or aluminum), then using the formula below you can calculate its weight in 1 linear meter of cable:
m (gram) = p x 3.14 × 100 (cm) x (R2 (cm) - r2 (cm))
p - metal density (lead - 11.3; aluminum - 2.9) R - outer radius of the shell (cm)
r - internal radius of the shell (cm)
Example 1: Cable ААШв 4×120. Four aluminum conductors with a cross section of 120 sq. mm. 4 × 0.324 g = 1.296 kg per 1 linear. m
and aluminum shell 2.9 × 3.14 × 100 x (22 - 1.852) = 526 g.
Example 2: MCSB cable 4×4 × 1.2. Four copper quads with a diameter of 1.2 mm. 4 × 4 x 0.010 = 0.160 kg per 1 linear. m
and lead sheath 11.3 × 3.14 × 100 x (1.32 - 1.182) = 1056 g.
copper density = 8.9
aluminum density = 2.7
For example: Weight of copper in 1 km of cable VVG 3x1.5 = 3*1.5*8.9 = 40.05 kg per 1 km.

Selection by table
Knowing the diameter of the wire, you can determine its cross-section using a ready-made dependence table. The table for calculating the cable cross-section by core diameter looks like this:
| Conductor diameter, mm | Conductor cross-section, mm2 |
| 0.8 | 0.5 |
| 1 | 0.75 |
| 1.1 | 1 |
| 1.2 | 1.2 |
| 1.4 | 1.5 |
| 1.6 | 2 |
| 1.8 | 2.5 |
| 2 | 3 |
| 2.3 | 4 |
| 2.5 | 5 |
| 2.8 | 6 |
| 3.2 | 8 |
| 3.6 | 10 |
| 4.5 | 16 |
When the cross-section is known, it is possible to determine the permissible power and current values for copper or aluminum wire. In this way, it will be possible to find out what load parameters the current-carrying core is designed for. To do this, you will need a table of the dependence of the cross section on the maximum current and power.

Converting watts to kilowatts
In order to correctly use the table of wire cross-section versus power, it is important to correctly convert watts to kilowatts.
1 kilowatt = 1000 watts. Accordingly, to obtain the value in kilowatts, the power in watts must be divided by 1000. For example, 4300 W = 4.3 kW.

Calculator for calculating cable cross-section by power and current
The algorithm for selecting the wiring cross-section based on load power includes the following steps:
- of the total power ( Ptotal ) of all electrical appliances connected using a conductor ( P1 - Pn) using the formula below :
Ptotal= P1+ P2+ P3+ Pn.
At the same time, for consumers such as electric motors and transformers, the reactive power given in the passport is converted into active power according to the following formula:
P = Q / cosφ.
- Search for values of simultaneity coefficients (K) and margin (J). In practical calculations, the K value is used equal to 0.8-0.85, J – 2.0.
- Calculation of the total active power ( P a ) taking into account correction factors K and J using the following formula:
Pa = Ptot• K• J.
- Select a conductor with the optimal cross-sectional area using the reference table (Fig. below).
Example No. 1
It is necessary to connect a group of electrical appliances with a total power of 5000 W to the three-phase input panel using a separate cable line laid in the wall.
On a note. The power of any electrical appliance can be found in its technical data sheet, instruction manual or on a special plate attached to its body.
The total active power of this group of devices, taking into account the simultaneity and reserve factors, will be equal to:
Pa = Ptot• K• J = 5000 • 0.8•2= 8,000 W or 8.0 kW.
For this power value, a copper conductor with a core cross-section of 2.5 mm square will be optimal.
Calculating the cross-section of a line based on the current supplied to it through a cable calculator has a procedure similar to the previous one:
- For each consumer, the current consumption is calculated using the formula I=P/U;
- The current values calculated for each device are summed up and multiplied by coefficients K and J;
- Using the reference table (Fig. below), a conductor is selected that has a cross-section capable of passing the design current.
Selecting the conductor cross-section based on the power and current of electrical appliances connected with it
Example No. 2
The total current strength of devices connected to a single-phase network is 15 A. Taking into account the coefficients K and J, it will be equal to 18 A. For laying such closed wiring and connecting devices with this total current value, a copper wire with a cross-section of 4.1 mm square is suitable.

Table of correspondence of wire diameters and their cross-sectional area
You don’t always want or have the opportunity to make payments in a store or on the market. In order not to waste time on calculations or to avoid making mistakes, you can use the table for the correspondence of diameters and cross-sections of wires, which contains the most common (normative) sizes. You can rewrite it, print it and take it with you.
| Conductor diameter | Conductor cross-section |
| 0.8 mm | 0.5 mm2 |
| 0.98 mm | 0.75 mm2 |
| 1.13 mm | 1 mm2 |
| 1.38 mm | 1.5 mm2 |
| 1.6 mm | 2.0 mm2 |
| 1.78 mm | 2.5 mm2 |
| 2.26 mm | 4.0 mm2 |
| 2.76 mm | 6.0 mm2 |
| 3.57 mm | 10.0 mm2 |
| 4.51 mm | 16.0 mm2 |
| 5.64 mm | 25.0 mm2 |
How to work with a table
To check, measure the diameter using any of the described methods, then check the table. It states that with such a cross-section of four square millimeters, the wire size should be 2.26 mm. If your measurements are the same or very close (there is a measurement error, since the devices are not ideal), everything is fine, you can buy this cable.
Stated sizes do not always correspond to real ones
But much more often, the actual diameter of the conductors is much smaller than the declared one. Then you have two options: look for a wire from another manufacturer or take a larger cross-section. Of course, you will have to overpay for it, but the first option will require a fairly long period of time, and it is not a fact that you will be able to find a cable that complies with GOST.

We are looking for the wire cross-section by diameter: formula
The wires in the cable have a circular cross-section. Therefore, when calculating, we use the formula for the area of a circle. It can be found using radius (half the measured diameter) or diameter (see formula).
For example, let's calculate the cross-sectional area of the conductor (wire) based on the size calculated earlier: 0.68 mm. Let's use the radius formula first. First we find the radius: divide the diameter by two. 0.68 mm / 2 = 0.34 mm. Next, we substitute this figure into the formula
You need to calculate it like this: first we square 0.34, then multiply the resulting value by 3.14. We obtained a cross-section of this wire of 0.36 square millimeters. This is a very thin wire that is not used in power networks.
Let's calculate the cable cross-section by diameter using the second part of the formula. It should be exactly the same value. The difference may be in thousandths due to different rounding.
S = π/4 * D 2 = 3.14/4 * 0.68 2 = 0.785 * 0.4624 = 0.36 mm 2
In this case, we divide the number 3.14 by four, then we square the diameter and multiply the two resulting numbers. We get a similar value, as it should be. Now you know how to find out the cable cross-section by diameter. Whichever of these formulas is more convenient for you, use that one. No difference.
| Conductor diameter | Conductor cross-section |
| 0.8 mm | 0.5 mm2 |
| 0.98 mm | 0.75 mm2 |
| 1.13 mm | 1 mm2 |
| 1.38 mm | 1.5 mm2 |
